2016-10-06MIPS: generic: Convert SEAD-3 to a generic boardPaul Burton1-1/+0
Convert the MIPS SEAD-3 board support to be a generic board, supported by generic kernels. Because the SEAD-3 boot protocol was defined long ago and we don't want to force a switch to the UHI protocol, SEAD-3 is added as a legacy board which is detected by reading the REVISION register. This may technically not be a valid memory read & future work will include attempting to handle that gracefully. In practice since SEAD-3 is the only legacy board supported by the generic kernel so far the read will only happen on SEAD-3 boards, and even once Malta is converted the same REVISION register exists there too. Other boards such as Boston, Ci20 & Ci40 will use the UHI boot protocol & thus not run any of the legacy board detect functions.

2016-10-06MIPS: generic: Introduce generic DT-based board supportPaul Burton1-0/+1
Introduce a "generic" platform, which aims to be board-agnostic by making use of device trees passed by the boot protocol defined in the MIPS UHI (Universal Hosting Interface) specification. Provision is made for supporting boards which use a legacy boot protocol that can't be changed, but adding support for such boards or any others is left to followon patches. Right now the built kernels expect to be loaded to 0x80100000, ie. in kseg0. This is fine for the vast majority of MIPS platforms, but nevertheless it would be good to remove this limitation in the future by mapping the kernel via the TLB such that it can be loaded anywhere & map itself appropriately. Configuration is handled by dynamically generating configs using scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc makes use of it. This allows for variations upon the configuration, eg. differing architecture revisions or subsets of driver support for differing boards, to be handled without having a large number of defconfig files.

2016-01-24MIPS: Add support for PIC32MZDA platformJoshua Henderson1-0/+1
This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.

2015-06-21MIPS: Loongson: Naming style cleanup and reworkHuacai Chen1-2/+2
Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.
